Harry Styles and Zayn Malik prove that they remain brothers despite the issues that befell One Direction earlier this year. Following the latter's breakup with fiancée Perrie Edwards, Harry Styles reportedly penned a personal note for his former band mate.

"Harry is a really nice guy and he proved that once again. He wrote a sweet and sincere email to Zayn about everything they had been through," said one source to Hollywood Life.

"He told Zayn how brave he thought he was over the past year, leaving the band and now calling off his engagement. It definitely touched Zayn."

Harry Styles and Zayn Malik are not the only ones leaning on each other. As per the same publication, Louis Tomlinson had a heartfelt phone call with his pal. The duo allegedly talked about the controversies they're currently in.

"They talked for a while about how crazy life had gotten for them. Zayn is single and going solo and Louis is going to be a dad!" said the insider. "There were even some tears shed during the call. They fight like brothers but they also laugh like brothers."

While Louis Tomlinson already confirmed his impending fatherhood, Zayn Malik is yet to speak out about his breakup with the Little Mix songstress. Reports have surfaced that apart from their hectic schedules, Perrie Edwards' constant nagging for a wedding date allegedly prompted the Bradford-born singer to end their engagement.

Nonetheless, the truth might come out this August 18 because the Little Mix is set to appear on James Corden's The Late Late Show.

"James has got a way about him, a cheeky way, where he is able to coax gems of information out of people. If anyone can get Perrie taking, it's him," claimed a television source to Mirror.
